JQuery Price Format

Created By Eduardo Cuducos and now maintened by Flávio Silveira. Go to Top Content

jQuery Price Format is a plugin to format input text fields or any HTML element as prices. For example, if you type 123456 in a input or set a p tag with this value, the plugin updates it to US$ 1,234.56. It is costumizable, so you can use other prefixes and separators (for example, use it to get R$ 1.234,55).


Version 2.0 — 26 Jan 2014

Now working with any HTML element.

Version 1.8 — 24 May 2013

Fix for not show the cents signal when limit is set to Zero. Added new option to show the plus sign.

Version 1.7 — 22 February 2012

Added new option to insert suffix and clear suffix. Added new function unmask, that return the value without mask.

Version 1.6 — 05 December 2011

Fixed issues for compress the script with YUI Compressor and Closure Compiler. Now we have the minified version for download.

Version 1.5 — 27 June 2011

Fixed some bugs with clearPrefix on initialize and with Keypad. Allow the del button and added new Option allowNegative (See the example).

Version 1.4 — 17 March 2011

Added new option to clear the prefix on blur (clearPrefix) to make more easier the process to put this data in a database. See the example

Version 1.3 — 16 April 2009

The issue about the keypad (v.1.2) is fixed.

Version 1.2 — 02 March 2009

Better user experience by decreasing the use of the keyup event, so avoiding user to see non-numerical chars or unformatted price while key is pressed.

Also, as the use of keydown, it is possible to navigate from one input to another with Tab key and send the form hitting Return key.

Version 1.1 — 09 February 2009

Settings options to limit max length (limit) and change the size of the cents field (centsLimit).
See the example.

Example 1 - Basic usage




This is the most basic usage. It loads default options: use US$ as prefix, a comma as thousands separator and a dot as cents separator.

Example 2 - Use with any HTML element





The same basic usage as above, but now using the value inside a H4.

Example 3 - Customize


    prefix: 'R$ ',
    centsSeparator: ',',
    thousandsSeparator: '.'


This is a costumized format like brazilians use: R$ as prefix, a dot as cents separator and a dot as thousands separator. Play with the options centsSeparator and/or thousandsSeparator to better fit your site.

Example 4 - Skipping some option


    prefix: '',
    thousandsSeparator: ''


You can skip some of the options (prefix, centsSeparator and/or thousandsSeparator) by set them blank as you need it in your UI.

Example 5 - Working with limits


    limit: 5,
    centsLimit: 3


You can set a limited length (limit) or change the size of the cents field (centsLimit) to better fit your needs. This features was included in v. 1.1.

Example 6 - Clear Prefix and Suffix on Blur


    clearPrefix: true


The default value of clearPrefix and clearSuffix is false. Both work in same way.

Example 7 - Allow Negatives


    allowNegative: true


The default value of allowNegative property is false. Obviously, zero values are not negative.

Example 8 - Add Suffix


    prefix: '',
    suffix: '€'


The default value of suffix is empty.

Exemplo 9 - Unmask function


var unmask = $('#example8).unmask();
alert(unmask); // alert 123456


Return the value without mask. Negative numbers will return the minus signal.

Exemplo 10 - Plus sign


    prefix: '',
    thousandsSeparator: '',
    insertPlusSign: 'true'


Sometimes show the plus sign can improve your usability. Since you allow this option you will automaticly allow the use of the minus sign.
